Initial misunderstandings, emails round trips with the community… standard communication process!

I do not know how others a seeing it, but reading about the process you use, I do not see anything like a wild bulk import. At least, it is very similar to the process I used when importing Canvec datasets.

Hi all,
Please accept my apology for this misunderstanding, I thought our presence for last OSM meeting and flowing emails in Talk-ca and with John were part of communication and discussion, we launched our wikipage two weeks ago, and we did not receive any feedback, so we thought to start import via JOSM.

as we expalined in our wikipage, we created the algorithm to detect the missing information, and then we check the quality of this information on JOSM on the top of OpenStreetMap, Bing Areal imagery, GeoBase Road network and some local municpal open data. the data is created initially through StatCan, however, we noticed the low quality of StatCan road segment geometry, so we deal with this issue by using complement dataset such as OpenStreetMap, Bing Areal imagery, GeoBase Road network and some local municpal open data. all created nodes and ways are carefully inspected visually using above dataset for more that 6 weeks.

Our final verification will be on the OSM server (on-line) to avoid or detect any issues. Our aim is having high quality address information in OSM for sake of community. we were very prudent from the first step to have a high quality source of information.

I hope that the community will accept our contribution and enjoy to use the data.

Best regards,

Mojgan

It seems that this import has started with no discussion. Here's the wiki

I had a skype call with Mojgan where we discussed some of the issues and
there was an email sent to talk-ca on Jan 12th 2016.

To me a couple of issues first are that the Stats Canada data was designed
for Stats Canada use, probably for the labour force survey and as such
provided the interviewer can see the address from where it is marked on the
map this is sufficent accuracy.  My concern would be about the accuracy of
the data.

Another issue is do we end up with duplicate addresses?  My concern would
be do we end up with the same address in two different locations?

I think a better solution would be to take a copy of the OSM database,
strip out the existing address data and drop in the stats data and use the
copy for their purposes.
